SAFETY INSTRUCTIONS
Please read the instructions carefully before using the equipment.
To use the equipment correctly, do not attempt to install, operate, maintain, or inspect the equipment until you have read
through this manual, installation guide, and appended documents carefully. Do not use the equipment until you have a full
knowledge of the equipment, safety information and instructions.
In this manual, the safety instruction levels are classified into "WARNING" and "CAUTION".
Note that the CAUTION level may lead to a serious consequence depending on conditions.
Please follow the instructions of both levels because they are important to personnel safety.
Forbidden actions and required actions are indicated by the following diagrammatic symbols.
In this manual, precautions for hazards that can lead to property damage, instructions for other functions, and other
information are shown separately in the "POINT" area.
After reading this manual, keep it accessible to the operator.

WARNING
●To prevent an electric shock, turn off the power and wait for 15 minutes or more before starting wiring
and/or inspection.
●To prevent an electric shock, ground the servo amplifier.
●To prevent an electric shock, any person who is involved in wiring should be fully competent to do the
work.
●To prevent an electric shock, mount the servo amplifier before wiring.
●To prevent an electric shock, connect the protective earth (PE) terminal of the servo amplifier to the
protective earth (PE) of the cabinet, then connect the grounding lead wire to the ground.
●To prevent an electric shock, do not touch the conductive parts.
WARNING
●To prevent an electric shock, do not operate the switches with wet hands.

ABOUT THE MANUAL
e-Manuals are Mitsubishi Electric FA electronic book manuals that can be browsed with a dedicated tool.
e-Manuals enable the following:
• Searching for desired information in multiple manuals at the same time (manual cross searching)
• Jumping from a link in a manual to another manual for reference
• Browsing for hardware specifications by scrolling over the components shown in product illustrations
• Bookmarking frequently referenced information
• Copying sample programs to engineering tools
If using the servo for the first time, prepare and use the following related manuals to ensure that the servo is used safely.

Interpreting servo parameter numbers
For a servo parameter which uses one particular digit to select a function, the position of its digit indicates the detail number of
the servo parameter, and the value in hexadecimal which is set to the digit indicates the selected function.
For example, the detail number of the servo parameter in the last digit is expressed as [Pr. PA01.0]. In addition, a servo
parameter which uses a combination of several digits to select a function, is expressed using "-" as seen in [Pr. PA01.0-1].
The following is an example of the servo parameter number PA01 with the setting values of "FEDCBA98" in hexadecimal.
• When setting a servo parameter with one particular digit
• When setting a servo parameter using a combination of several digits
For example, if the servo parameter name is "Function selection A-1", the setting digit name is "Forced stop deceleration
function selection", and the setting digit is the fourth last digit in PA04, the servo parameter is expressed as shown below.
[Pr. PA04.3 Forced stop deceleration function selection]

*1 This value is applicable when all I/O signals are used. Reducing the number of I/O points decreases the current capacity.
*2 If closely mounting the servo amplifiers, operate them at an ambient temperature of 0 ˚C to 45 ˚C or at 75 % or less of the effective load
ratio.
*3 This current value is applicable when a 3-phase power supply is used.
*4 If using 1-phase power supply in combination with the servo motor of 750 W or higher, operate the servo amplifier at 75 % or less of the
